Referring now to the drawings in detail 4Q the invention will nowbe fully described.

The wringer may be used with a washing machine or other apparatus and is shown in association with a wringer head H.` This head may be supported by a tube 4 depending from the lower side thereof. A drive shaft 6 is journalled in the housing by means of a suitable bearing construction 8 associated with the tube and housing and carries on its upper end a driving pinion 10.

The tube may be supported from a Washplan view of the wringer shown 1931. serial Np. 52ans. i

This is Etovbe-fdistinguished fromgthe .usual construction wherethe'drive roll shaft is journalled in a frame. In this ,construction the usual frame :is eliminated so that the structure-is not/,only simple in form but is eieient in its operatonaswell. y

Carriers 40 .are, slidable inlthe guidesO and 32 and theserhaveslidablein their upper ends boxes 44. .Adjust'able plugs 46 in the upper ends of the members 40 are arranged. for screwing intoand rout of saidlmembers to vary the tension Vofsprings 48 interposed between, the plugs 46 and bottom walls48 of the boxes-44 so as to -yieldingly urge the boxes downwardly of the carriers. 90 An upper roll 50'is rotatable on a shaft 52 the ends 'ofwhich are.` receivable in slots 53 of the boxes. These slots are arranged so that the upper sides thereof bear on the upper sides of the ends of the shaft 52 where- 95 by the springs 48 will urge the boxes downwardly of the carriers and yieldingly hold the roll 50 in contact 4'with the driving roll 56 when the carriers are in a lower position. Slots'l and 54 in the guides and carriers 106 disposed and provided with offset portions 65, so as to moves-fthe rodzback .and forth as` it is swung along the slot. In this way the hub 12 is moved in one direction or the ohea permit relative movements of the shaft 52, boxes, carriers and guides.

A collar rotatable around the hub 12 Within the housing is movable back and forth therewith and has a rod 62 extending upwardly therefrom which passes through a slot 647ffin .-uthe iuppei. side ofthev housing. This slot -(as shown in Fig. 3) is anglarly to move the shaft and gears 22 and 24 to engage either one of the-gears :with the'v pinion 1 2.

Should 'it lbe necessary Vfto release the roll 50 the levers 'may be's'wung in one direction or the other yso that the pins'may travel upwardly of the slot72. A lever 70 is shown 'in releasing position by dot-dash lines in Fig. 7. I l

offacilitate ready'operation of the levers 70 they are connected by bars o'r rods 8() at -opposite' sides of the'wringer which have their ends ixe'd in the ends of arms 82 of said levers f 70; 'Alongitudinally extending member or members y84 may be fixedto the ,upper ends of 'guides' 30 and v32, to serve as a hand grip to ftacilitate-tilting of the mechanism. A loclr 86 in the formof a ballis urged upwardly by .a spring 88 and into engagement with an aperture 90 in the lower side of collar G0 and be instantly swung in one direction or the other, the upper roll is relieved of spring pressure and 1n this way the'operator 1s safeguarded against injury.

As has been stated, the parts are shown in Figs. f1, 2, 3, and 6in a-.neutral position wherein the driving shaft 14 is disconnectedfrom the driveA shaft 6, but-"in the operation of lfthe wringei ythe 'parts will vvbe tilted `in ione 'direc'- tion or=the other-or to such a position as shown infl`igl7'."' 'Tf1 y 'The neutral position may 'be called a safety position because in' this positionfthe 'driving and driven gears cannot beoperatively:eenn-e'cted. When'theLWrin'gerA is swung tog-a tiltedV position-however the gears ima-y' be `connected for' the'roll'drivin'goperationand ing a tilted position the upper Vroll is releasabiy held l'in' Contact with {theflowerl' roll. 'f

A Alug l80 ef the guidevadj ae'ent'the housing has -a'p'artf 82 whichl-fproj ects -over 'iony tof'the housing andthis is4 receivable inai 'transverse slot between projectionsv 84 on the'fupper iside of the housing. In-.aineutral position the flug 82 lies within the slot between the projections so lthat the Wringer-parts are held againstreciprocating movementslto- 'engage the. gears.

When it is desired to tilt thewrin'ger -fr operation 'it may be tilted'in one direction or the other from' the'neutral position vsothatthe lug 82 may pass back and forth in longithdinal lslots 87 between opposite sides of -the member 84 and the inner sides ofmembers 88 carried on the upperside of the housing. The ends of these lugs 88 act as stops also to limit thetilting movements'of the-wringer in one direction or the other. I

It will be assumed that it is desired for 0peration to tilt the wringer to the position shown in Fig.A 7. In this case the wringer is tilted rearwardly so that ythe lug 82 Yabuts the inner end of lug 88. Now the wringer'may be lmoved back andfforth, andtherod 62 may be moved along the slot 64 in either direction to cause either of the gears 22 or 24' to be meshed with the driving gear 10. With the parts in neutralpositionthe rod62 .may not be moved relative to slot 64 because the member`GO is held against-axial movements.

With one of the driven gears in mesh with the driving gear the shaft 14 is rotated. In order to releasably hold the upper roll 50 in yielding engagement with the lower drive roll 8G the levers 70 are swung so that the pins 74 lof the carrier are4 within the slots 73 of the levers.

Clothes are passed by the operator through to effect swinging movements l tion thereof to I of engagement with .means associated with said with said barrel and an the direction of the arrow F. In case it is desired or-necessary to release the upper roll the operator has merely to contact with one of the levers 7 0 or a rod 80 connecting the same thereof. As shown in Fig. 7, when the levers 70 are swung to the dot-dash position the pins 74 pass upf wardly in slots 72 thereof so that the rolly 50 is free to be elevated by reason ofA anything which may be between the rolls 36. and 50.

or instanoe,-if an operator has a hand h caught between the rolls as s oon as the lever 7 0 is moved the hand will n be elevated thereby, and in that way the hand is relieved of the pressure and the operator is guarded against A In any operative position the upper roll is yieldingly held are releasable y the operator so that the 'roll 50 is freely movable away from the roll 86.

Variouschanges may be made in the form of the apparatus without departing from the spirit and scope of the invention and it is therefore desired to be limited by the appended claims ratherthan by the foregoing description. f'
